According to the report, Flav's fiancee claims her earring was ripped out during the altercation ... and her 17-year-old son jumped in to defend her.

At that point, the report continues, Flav grabbed two knives and chased her son around the house -- eventually kicking down a locked door to get to him. Flav then allegedly threatened to kill him.

According to the report, Flav denied chasing the teenager with the knives. He also denied the whole death threat thing.
